Title: Improvements relating to the metallic banding or wiring of packing cases
IPC: B65B13/32
Filed: 1935-09-18
Abstract: 458,197. Binding packages ; welding. SUTTON, J. R., 2, Knoclaid Road, Tue Brook, Liverpool. Sept. 18, 1935, No. 25856. [Class 83 (iv)] [See also Group I] A machine for binding packages with metal bands or wires comprises a base positioned on the package and provided with gripping and tensioning means and with one or more pairs of electric spot welding electrodes, the points of which are shrouded during welding so as to prevent sparks or molten metal from igniting combustible material in the vicinity. On the base 1, which may be flat or rounded, is mounted at one end a rotary spring-actuated eccentric claw 2 for clamping one end of the band and releasable by a lever 9. At the other end mounted on an eccentric 11 on a shaft 12 is a knurled tensioning wheel 4, which is brought into contact with the other end of the band, after it has been wound round the package, by operation of a thumb lever on the shaft 12, tensioning being then effected by rotating the wheel by a ratchet lever 17. The ends of the band are overlapped between the electrodes 27, 32 of a spot welding apparatus secured to the base, the first-mentioned end passing under and the second-mentioned end over an anvil 56. The fixed electrodes 32 are mounted in a fibre insulation pad 33 and are electrically connected by a strip 41 and lead 40 to the terminal 35. The electrodes 27 are carried by spring-retracted plungers 26, which reciprocate in an insulating block 23 secured in a rectangular cage 21 forming a slide, which is raised by springs 22 and is depressed by a cam 48 on a hand rotated shaft 43 through a bridge piece 54 supported by springs 55. The plungers, which are electrically connected by contact strips 37 and leads 36 to a terminal 34, are depressed successively to effect the welds, after the slide has been pressed into contact with the work, by a pair of cams 47, 49 on the shaft 43 through spring-controlled mushroom tappets 50. The lower end of the slide is provided with a fireproof pad 29 of fibre, wood or asbestos containing loose flanged sleeves 28 for shrouding the points of the movable electrodes, these sleeves engaging the lower ends of the plunger springs 25. One side 21b of the case projects below the base of the pad so that when the latter is pressed down it takes into a slot 1a in the base. An asbestos apron 10 also extends round the pad. Alongside the slide 21 is a shear blade 6, which is reciprocated by a cam 46 to sever the surplus part of the right hand end of the band prior to welding. Adjustable lateral stops 60, 61 are provided to suit bands of different sizes. Current is supplied through a switch which may be operated by an arm 58 on the cam-shaft through a Bowden control 57. In the case of a wire tie the electrodes may be V-grooved to form a grip device for holding the ends in contact during welding. According to the Provisional Specification the fixed electrode may consist of a thin-metal blade. Further, cutting may be effected simultaneously with or immediately after welding.

Patent GB-773611-A (GB)
Title: Resol resins
Inventor: FRASER DONALD ALEXANDER
IPC: C08G8/10
Filed: 1954-09-10
Abstract: Resol resins are made by condensing a molar excess of phenolic material with formaldehyde in the presence of a strongly basic oxide or hydroxide of a divalent electropositive metal at a pH greater than 7 to produce a non-heat hardenable novolak resin which is then reacted with formaldehyde at a pH above 7, the condensation being stopped before the resol becomes insoluble. The molar ratio of condensed formaldehyde to phenol in the final product exceeds 1 : 1. The phenolic material comprises phenol, meta-cresol, meta-ethyl phenol and mixtures thereof amongst themselves or with other phenolic compounds.  Suitable catalysts for the first stage of the process are the oxides and hydroxides of barium, strontium, calcium and magnesium, whilst suitable catalysts for the second stage include the alkali metal hydroxides and carbonates, alkaline earth metal oxides and hydroxides, ammonia and organic bases.  In the example, 3000 parts of phenol, 658 parts of formalin (36.35 per cent) and 30 parts of calcium carbonate are refluxed for 30 minutes and water distilled off to a temperature of 160 DEG  C. and the excess phenol removed; 252 parts of the resultant novolak are mixed with 277 parts of water and 59.2 parts of 151.6 parts of formalin added and the solution heated to 90 DEG  C.  The product was suitable for use as a plywood adhesive.

Filed: 1945-10-09
Abstract: 601,860. Copying lathes; chucks. COX, L. N. (Lavietes, D. P.). Oct. 9, 1945, No. 26272. [Class 83 (iii)] Chucks.-A chuck for holding briar &c. pipe blanks is of the bevel closing type and comprises a spring-biassed, cam-actuated pin having a conically-shaped head which is moved axially to engage a series of jaws pivoted and depending from a base, the pin extending through the base to be threadably engaged by a bearing stud associated with the cam member, Ó resilient pad being interposed between the base and the cam face against which the cam reacts. The base 21 is supported by a frame 19 adjustably mounted on a block having a shank extension 18 for mounting on the rotatable shaft of the machine. The jaws 20 are formed with heels pivoted on the base, and are moved outwardly to gripping position by the head 23 of the pin 22 being retracted by the cam member 33 on rotation by a handle 36 about the bearing stud 29 which also threadably engages the pin. A portion of the pin adjacent the head is tapered to engage the heels of the jaws for releasing their grip when the head 23 is moved outwardly from the jaws. The cam bears against a resilient member 32 thereby preventing undue gripping pressure by the jaws. The threaded engagement of the pin and bearing stud permits the use of the chuck for gripping workpieces of varying internal diameter. A spring 34 urges the pin head outwardly from the jaws. In another form, the pin is threaded into a member inserted in a short tube transversely disposed to the pin, spring pressure between the insert and wall of the tube maintaining these parts in correct relationship and providing resilient reaction to the cam member whilst spring means connecting the tube and the base maintains the assembly within a supporting frame attached to the shank member. The cam member is in the form of a ring carrying the tube assembly. Copying-lathes.-The chuck may be applied to the machining of the wooden bowls of smokers' pipes wherein the work is shaped according to a pattern and tracer, the spring action behind the pins 22 enabling the pins to eject the work. The chuck and a pattern are mounted at opposite ends of a spindle journalled at its centre in a frame having a rocking and sliding movement on a bar to present the work and pattern respectively to a rotary cutter and a follower mounted on a stationary spindle.

Filed: 1931-09-22
Abstract: 379,873. Road-traffic signals on vehicles. SPARGO, R. J., N'Kana Mine, N'Kana, Northern Rhodesia, Africa. Sept. 22, 1931, No. 26457. [Class 118 (ii).] In manoeuvre-signalling apparatus of the kind described in Specification 377,270, the signals 4 .. 8 are selectively illuminated by appropriate movements of a single universally mounted switch member 27, which is capable of (a) right, left, forward, and backward motion in slots 23 .. 26 to close contacts giving right, left, ahead, and reverse signals 4 .. 7 respectively, (b) a pull-up movement through the ball bearing 29 to close a contact for the stop signal 8, (c) a rotational movement closing contacts simultaneously for the signals 7, 4 indicating " rightabout turn," and (d) a push-down movement to sound the hooter by causing the casing 18 to be depressed against the action of a spring 19 and a contact 74 to touch the outer earthed casing 20. Each movement of the switch for the purpose of signalling is arranged to break the circuit of the head-lamps 11. Springs 30 restore the member 27 to its neutral position, unless it is moved so as to be held by spring- pressed ball catches, such as 61. The ball 29 receives current from a rubbing contact, and the current passes by way of the stem 27 to a collar 40 co-operating with a series of spring contacts. A tell-tale lamp 10 is illuminated as each signal is given. A spiral spring 85 restores the stem to its neutral position after the rotational movement. The stem is constrained in its movements so that only one signal at a time can be given. To cause flashing of the signals, a thermo-electric switch or like automatic interrupter 96 is included in the main circuit.
